Different techniques for different parts of the country, I suspect...

I keep mine covered at night to reduce heat loss.
Not running the pump at night helps too.

You must live up north... I'm in the Houston area and a few years ago,
I had a house that had a pool... During the latter part of the summer,
the water temperature gets into the 90Fs...

Yep, I'm in NJ.
I've been to Houston, the climate was great but I found the flat terrain

Our pool is in partial shade. It can reach 90F, when I run the heater.
Without that, a peak temperature in most years is 82F.
